Mobile phone {PORTABLE TELEPHONE}

In recent years, mobile phones are widely used among ordinary people, and many young people in particular own mobile phones for personal communication. Recently, various techniques for mobile phones have been developed by technicians, and some mobile phones also have specific functions as game devices in addition to mobile phone functions. For this reason, there is a strong demand for further development and improvement of functions as game devices for mobile phones.

An object of the present invention is to provide a cellular phone which is equipped with a novel function as a game device, and in particular, realizes mock performance of musical instruments.

The present invention relates to a cellular phone that generates a musical sound such as a melody sound or a rhythm sound to respond to an incoming call or play a game.

1 is a block diagram showing an electronic configuration of a cellular phone according to a first embodiment of the present invention.

Fig. 2 is a block diagram showing the electronic configuration of the cellular phone according to the second embodiment of the present invention.

The cellular phone of the present invention is basically designed to realize game device functions such as music games in addition to the cellular phone function. Based on the cellular phone function, the cellular phone wirelessly establishes a line connection with an external telephone terminal, for example, to an existing telephone line network constituted by a base station or a mobile switching center. Here, the cellular phone can generate a musical sound or a rhythm sound of a predetermined music in response to an incoming call. Game machine functions are especially realized by vibration devices such as vibration sensors and vibration motors. That is, when the user swings the cellular phone in accordance with the rhythm sound, the vibration device generates a vibration pulse, which is compared with the rhythm pulse. Thereafter, a score is scored for the rocking motion of the cellular phone by the user according to the time difference detected between the vibration pulse and the rhythm pulse, and displayed on the screen of the display portion. That is, the user can play a music game by swinging the mobile phone, such as maraca, in accordance with the rhythm.

On the other hand, when the vibration motor is installed in the cellular phone, it is possible to generate vibration in response to an incoming call, and the vibration applied to the cellular phone can be detected in response to the counter electromotive force generated by the vibration motor. Back EMF can also be used to charge batteries in mobile phones.

The present invention will be described in detail with reference to the accompanying drawings.

1 shows an electronic configuration of a cellular phone K according to a first embodiment of the present invention. In Fig. 1, reference numeral 1 denotes a central processing unit (CPU) which collectively controls each part or circuit of the cellular phone K, and code 2 stores a program executed by the CPU 1, A read only memory (ROM) for storing incoming melody data used for generating an incoming melody sound for informing the user of the incoming call to the cellular phone K. Reference numeral 3 denotes a random access memory (RAM) used for temporary storage of data. The RAM 3 temporarily stores telephone numbers used for dial processing and music data used for games. On the other hand, the RAM 3 has a battery backup. Reference numeral 4 denotes an operation unit including a numeric key for inputting a telephone number and a function key for inputting a command or command. Reference numeral 5 denotes a liquid crystal display unit or a display unit composed of a display control circuit.

Reference numeral 6 denotes a communication unit connected to the antenna 7. The communication unit 6 transmits the transmission data by the carrier wave through the antenna 7, demodulates the incoming signal received by the antenna 7, generates the incoming data, and sends it to the voice processing unit 8. In addition, the microphone 9 captures the voice of the user of the cellular phone K, converts it into a voice signal, and sends it to the voice processor 8. The voice processing unit 8 converts the voice signal into digital data and compresses it, and supplies the same to the communication unit 6. Moreover, the voice of a person using a telephone terminal (not shown) communicating with the cellular phone K is received by the communication unit 6 and converted into voice data. As a result, the audio processing unit 8 converts the audio data output from the communication unit 6 into an analog audio signal and sends it to the speaker 10.

Reference numeral 13 denotes a musical tone memory into which music data given by the CPU 1 is written. That is, the musical sound memory 13 stores the incoming melody data for the incoming melody sound generation and the game music data, which will be described later. The controller 14 writes the music data from the CPU 1 into the musical tone memory 13. Here, the music data includes melody data, timing data and rhythm data. As a result, the controller 14 reads the melody data from the tone memory memory 13 and outputs the melody data to the sound source circuit 15 in accordance with the timing data. In addition, the controller 14 generates a pulse signal which designates the timing of generation of the rhythm sound in accordance with the rhythm sound data, and outputs it to the rhythm sound source 16.

The sound source circuit 15 is a circuit which forms a digital sound signal by the FM method or the PCM method. That is, the sound source circuit 15 forms a digital melody sound signal according to the melody data output from the controller 14 and sends it to the digital-to-analog converter (DAC) 18. The digital / analog converter 18 converts the digital melody sound signal output from the sound source circuit 15 into an analog melody sound signal and sends it to the mixer 20. The rhythm sound source 16 generates a digital rhythm sound signal according to the pulse signal output from the controller 14 and sends it to the digital-to-analog converter (DAC) 19. The digital / analog converter 19 converts the digital rhythm sound signal output from the rhythm sound source 16 into an analog rhythm sound signal and sends it to the mixer 20. The mixer 20 mixes analog melody sound signals and analog rhythm sound signals respectively output from the digital / analog converters 18 and 19. In this way, the mixer 20 generates a mixed signal and sends it to the speaker 21.

Reference numeral 23 denotes a vibration sensor which senses the shaking vibration imparted to the cellular phone K by the user. When the output of the vibration sensor 23 exceeds the predetermined threshold level, the vibration detection circuit 24 generates a pulse and sends it to the rhythm difference detection circuit 25. That is, as long as the output of the vibration sensor 23 exceeds a predetermined threshold level, the vibration detection circuit 24 generates a pulse signal and sends it to the rhythm difference detection circuit 25. When the user presses a key of the operation unit 4 to start the game, the CPU 1 issues a game start signal to operate the rhythm difference detecting circuit 25. That is, after the CPU 1 issues a game start signal, the rhythm difference detection circuit 25 is output from the controller 14 to detect a pulse that designates the rhythm sound generation timing and the shaking vibration of the mobile phone K. The time difference from the pulse output from the detection circuit 24 is measured. Thereafter, the measured time difference is sent to the CPU 1.

Next, a detailed operation of the cellular phone K having a game device function in addition to the cellular phone function will be described. First, the cellular phone function of the cellular phone K will be described.

When the caller receives from the telephone terminal, the communication unit 6 receives the incoming signal by the antenna 7, demodulates the incoming signal, generates the incoming data, and sends it to the CPU 1. Upon receiving the incoming data, the CPU 1 accesses the RAM 3 and stores the caller's telephone number. Thereafter, the CPU 1 reads out the incoming melody data from the ROM 2 and sends it to the controller 14. The controller 14 writes the incoming melody data into the tone memory 13, and sequentially reads out the incoming melody data from the tone memory 13 and supplies it to the sound source circuit 15. FIG. As a result, the sound source circuit 15 generates an incoming melody signal and converts it into an analog signal by the digital-to-analog converter 18. The analog signal is supplied to the speaker 21 through the mixer 20, whereby the speaker 21 generates an incoming melody sound.

When the user of the cellular phone K presses the receive button (not shown) of the operation unit 4, the CPU 1 issues a ring tone stop command to the controller 14. In addition, the CPU 1 issues a line connection command to the audio processing unit 8 and the communication unit 6. Therefore, the line connection between the cellular phone K and the caller's telephone terminal is established. Thereby, the audio signal of the microphone 9 can be transmitted to the caller. In addition, the voice processing unit 8 outputs a voice signal based on the caller's voice to the speaker 10. As a result, the speaker 10 generates the caller's voice.

At the time of call transmission, the user of the cellular phone K operates the numeric keys of the operation unit 4 to input the telephone number of the call partner, and then the user presses the transmission button (not shown) of the operation unit 4. By inputting the telephone number by the numeric keys, the CPU 1 writes the telephone number into the RAM 3. When the user presses the send button, the CPU 1 sends the telephone number temporarily stored in the RAM 3 to the communication unit 6. Thereafter, the communication unit 6 transmits a signal indicating the telephone number by a carrier wave using the antenna 7. As a result, a call signal corresponding to the telephone number is transmitted to the telephone terminal of the call partner. When the line connection with the telephone terminal of the call counterpart is established, the CPU 1 issues a line connection command to the communication section 6 and the audio processing section 8. As a result, the call between the microphone 9 and the speaker 10 can be communicated.

The above cellular phone function is generally used in a conventional cellular phone.

Next, the game device function of the cellular phone K will be described. In this case, the user calls a music download center (not shown) and requests distribution (or download) of the music. The music download center is a computer facility dedicated to the distribution of music information and data. Upon receiving a request from the user or subscriber of the telephone via the telephone line, the music download center distributes the music data of the required piece of music for a fee. That is, the music download center distributes music data including melody sound data or rhythm sound data to the user or subscriber. When the user of the cellular phone K requests the distribution of a particular piece of music, the music download center downloads the corresponding music data to the cellular phone K, and the music data is received by the communication unit 6 and the CPU 1 Sent to). The CPU 1 writes the downloaded music data into the RAM 3. In this case, the user of the cellular phone K can request distribution of a plurality of pieces of music at the music download center, and the plurality of pieces of music are written into the RAM 3.

When downloading and receiving music data of a plurality of pieces of music requested by the cellular phone K, the user can select one of the pieces of music by operating a predetermined key of the operation unit 4. In that case, the CPU 1 detects key operation by the user and reads out music data of the selected piece of music from the RAM 3. The read music data is sent to the controller 14 and written to the musical tone memory 13. After that, the user operates a predetermined key on the operation unit 4 to start the game. The CPU 1 detects the key operation and issues a game start command to the controller 14 and the rhythm difference detection circuit 25. As a result, the controller 14 sequentially reads out the music data including the melody data, the timing data, and the rhythm sound data from the music memory memory 13. The controller 14 outputs the melody data to the sound source circuit 15 according to the timing data, and outputs a pulse signal to the rhythm sound source 16 which designates the rhythm sound generation timing according to the rhythm sound data. As a result, the speaker 21 generates the melody sound or the rhythm sound of the selected piece of music.

In accordance with the music, the user grabs and shakes the mobile phone K, like Maraca, a type of percussion instrument. When the user shakes the cellular phone K, the shaking vibration is given to the cellular phone K, which is detected by the vibration sensor 23 and a pulse is output. That is, the vibration detection circuit 24 outputs a pulse signal corresponding to the output of the vibration sensor 23 to the rhythm difference detection circuit 25. Thereby, the rhythm difference detection circuit 25 inputs the output pulse of the vibration detection circuit 24 which detects a fluctuation | vibration vibration, and the output pulse of the controller 14 which designates the rhythm sound generation timing. The rhythm difference detection circuit 25 continuously detects the time difference of the pulses as long as the user shakes the mobile phone K strongly and beyond the predetermined threshold level. As a result, the rhythm difference detecting circuit 25 generates time difference data for each of the output pulses of the controller 14 and continuously sends them to the CPU 1. The CPU 1 sequentially writes the time difference data into the RAM 3.

When the cellular phone K finishes reproducing the music based on the music data written into the music memory memory 13, the controller 14 issues an interrupt signal to the CPU 1 indicating the end of the reproduction. Receiving the interrupt signal, the CPU 1 sums up the time difference data written in the RAM 3. As a result, the total of the time difference data is displayed on the screen of the display unit 5 as the score of the user who played the music game.

In the above embodiment, the cellular phone K is designed to generate a rhythm pulse in accordance with the rhythm data included in the music data. The present embodiment can be modified to extract rhythm pulses from melody sound data. It is also possible to change this embodiment to stop the generation of the rhythm sound during the game.

Next, a second embodiment of the present invention will be described with reference to FIG. 2 showing an electronic configuration of the cellular phone K1. In FIG. 2, the same parts as in FIG. 1 are denoted by the same reference numerals, and description thereof is omitted as necessary.

Unlike the mobile phone K shown in FIG. 1, the mobile phone K1 shown in FIG. 2 is provided with a vibration motor 26 and a diode 27 instead of the vibration sensor 23 and the vibration detection circuit 24. . On the other hand, the cellular phone K1 shown in FIG. 2 includes a battery 28 and a power supply circuit 29, which are also used in the cellular phone K of FIG. 1, but the illustration is omitted. The vibration motor 26 is a direct current motor in which the vibration member is unbalanced on the rotating shaft. When the rotating shaft rotates by operating the vibration motor 26, an unbalanced movement is applied to the vibration member to cause vibration. The diode 27 is provided for reverse current prevention.

In the cellular phone K1, the user can select the vibration by the vibration motor 26 instead of the generation of the incoming melody sound by operating the keys of the operation unit 4. In that case, the CPU 1 issues a drive command to the vibration motor 26 upon reception. As a result, the cellular phone K1 operates the vibration motor 26 to generate vibration without generating an incoming melody sound in response to an incoming call.

Next, the game device function of the cellular phone K1 will be described. In this case, the user cuts off the power supply to the vibration motor 26. As with the cellular phone K shown in Fig. 1, the cellular phone K1 executes the same processing, so that the speaker 21 generates the musical sound of the selected specific musical tune. When the user shakes the mobile phone K1 in accordance with the music of the particular piece of music, the rotating shaft of the vibration motor 26 rotates due to the vibration of the mobile phone K1. By forced rotation of the rotary shaft, a "pulse type" counter electromotive force is generated in the coil of the vibration motor 26. The counter electromotive force is supplied to the rhythm difference detecting circuit 25. Thereafter, the rhythm difference detecting circuit 25 detects a time difference between the pulse of the counter electromotive force and the rhythm pulse output from the controller 14. The rhythm difference detection circuit 25 generates time difference data and sends it to the CPU 1. That is, the mobile telephone K1 is characterized by using the vibration motor 26 instead of the vibration sensor 23 shown in FIG.

The counter electromotive force is supplied to the battery 28 through the diode 27 to charge the battery 28. This means that the cellular phone K1 uses the vibration motor 6 as a vibration source and also uses it as a power source for charging the battery 28 while the user enjoys a music game.

As described above, the present invention has various effects and technical features, which are described below.

(1) The cellular phone of the present invention detects a time difference between a rhythm pulse corresponding to the rhythm of a piece of music and a pulse generated when the user swings the cellular phone in accordance with the piece of music. In addition, a new function is introduced in the mobile phone to automatically score the score of the music game according to the time difference between the rhythm pulse and the pulse in response to the user's movement. As a result, it is expected that mobile phones equipped with the above functions will attract people's attention and arouse new demands in the market of mobile phones and game machines.

(2) Vibration detection of mobile phones is realized not only by the vibration sensor but also by the vibration motor. Vibration motors are used to generate vibrations in response to incoming calls from the caller. In addition, the vibration motor can be used as a sensor because the vibration motor generates counter electromotive force in response to the applied vibration. Moreover, back EMF can be used for battery charging. Thereby, the mobile telephone provided with the vibration motor and which realized the game machine function of the present invention can be easily manufactured without investing new equipment in the existing telephone manufacturing facility. This results in a reduction in the manufacturing cost of a new cellular phone having a game device function.

Finally, the present invention need not be limited to the above embodiments, and therefore, various changes can be made without departing from the essentials within the scope of the invention.
